- Subject: [patch/rfc] post-process the `maint print architecture' from gdb_mbuild.sh
Hello,
The attached patch modifies the gdb_mbuild.sh so that it post-processes
the output from each target's `maint print architecture' command.
The post processing does two things:
- (using addr2line) replaces <0xNNNN> with the name of the corresponding
function / variable
- strips off any leading path info included in any file name paths
Doing this makes the task of comparing the `maint print architecture'
output from separate gdb_mbuild.sh runs easier - functions and file
names are identical.
thoughts?

* gdb_mbuild.sh: Edit the output of `maint print architecture'
replacing hex constants with function names and stripping leading
file name directory prefixes.
